Whitespace & Indentation Cleaner

Clean up messy text or code in one paste. Strip trailing whitespace, collapse runs of blank lines, swap tabs for spaces (or vice versa), normalize CRLF/LF/CR line endings, and replace weird Unicode spaces with plain ASCII — with live before/after stats and toggleable rules so you only touch what you want.

Tool Introduction

Tool Overview

Whitespace bugs are the silent productivity drain — emails with double spaces, code reviews with mixed indentation, CSV exports with no-break spaces hiding in cells. This tool gives you a focused interface for the common cleanups: trim each side independently, collapse internal runs, drop or merge blank-line gaps, convert between tab and space indentation at any width, and rewrite line endings to LF, CRLF, or CR. Everything runs locally.

Use Cases

Normalize indentation when pasting code from a chat or browser
Strip trailing whitespace before committing to git
Convert CRLF line endings to LF for Linux build environments
Remove no-break spaces and other weird Unicode whitespace from CSV exports
Clean up email content with double spaces and inconsistent line breaks

Input/Output Examples

Trailing trim + collapse blank lines + tabs→spaces + normalize Unicode spaces.

Input Intent

  function   hello (  name  )   {
  \tconsole.log(  "hi " +  name );  


   return  true;
}

Output Intent

function hello ( name ) {
  console.log( "hi " + name );

  return true;
}

FAQ

Will this corrupt strings inside code?+

Be careful with 'collapse internal spaces' and 'spaces to tabs' on code that has spaces inside strings or significant alignment — those run on every character including string contents. For most cleanups, trim and blank-line rules are safe.

What counts as a Unicode space?+

No-break space (U+00A0), em/en spaces, thin space, hair space, zero-width space, ideographic space, and similar — all the troublemakers that look like regular spaces but break grep, diff, and CSV parsing.

Why might I want CR or CRLF endings?+

CRLF is the Windows default and is required by some Windows-only tools and protocols. CR is the classic Mac OS 9 ending and rarely useful today. LF is the modern default for Linux, macOS, and most build tools.
